Abstract

Methotrexate (MTX) is a folic acid analog with anti‑proliferative (anti‑neoplastic, cytotoxic), immunosuppr­essive and anti‑inflammatory properties, which has been used in the treatment of various cutaneous disorders, such as psoriasis, keratoacanthoma, pityriasis rubra pilaris, atopic dermatitis, mycosis fungoides, bullous skin diseases, systemic sclerosis, morphea, lupus erythematosus, dermatomyositis and crusted scabies. Inhibition of cell proliferation is explained through its role in blocking DNA/RNA synthesis, by inhibiting dihydro­folate reductase, necessary for the production of pyrimidine and purine nucleotides. An anticancer effect can be related to α‑oxoaldehyde metabolism (MTX increases methylglyoxal levels). Its anti‑inflammatory property is based on the inhibition of 5‑aminoimidazole‑4‑carboxamide ribonucleotide transformylase, thus increasing intracellular and extracellular adenosine, a purine nucleoside with anti‑inflammatory effect. This drug can limit inflammation by scavenging free radicals and decreasing malondialdehyde‑acetaldehyde protein‑adduct production. Moreover, the anti‑proliferative and anti‑inflammatory effects can also be related to inhibition of the DNA methylation pathway, thus inhibiting methionine formation. The aim of the present study was to report various dermatological cases from our daily practice that demonstrate the efficacy of MTX in the treatment of cutaneous diseases, highlighting different mechanisms of action: its anti‑inflammatory effect in psoriasis and its anti‑proliferative, and anti‑neoplastic effect in well‑differentiated squamous cell carcinoma or in keratoacanthoma. Moreover, different administration pathways and doses are addressed. Assessment of the treatment plan, clinical improvement of cutaneous lesions, biologic evaluation, final aesthetic result, quality of life, as well as potential adverse effects and drug tolerance related to each case mentioned.
